Effect Of Anabolic Steroids Consumption On C- Reactive Protein (CRP) In Bodybuilders
H Arazi, M Ebrahimi, K Hosseini,
Volume 4, Issue 3 (3-2011)
Abstract

Background and Aim: Prevalence of anabolic steroids (ASs) consumption among bodybuilders has increased progressively. Therefore, the purpose of this study was to evaluate the effect of ASs consumption on C-reactive protein (CRP) in bodybuilders.

Materials and Methods: Sixty healthy men (age: 24/1± 9/1yr weight: 77±10 kg and height: 172±12 cm) participated in the study voluntarily. These subjects were selected from three groups. First group (FG) was bodybuilders who consumed ASs (n=20), second group (SG) was bodybuilders who did not consume ASs (n=20) and third group (TG) were untrained subjects as control (n=20). Blood samples were collected in fasting state (12 hours) at 09:00 for CRP assessment. Strength and volume of the forearm, pectoral major and femur muscles were measured via 1RM test and muscle circumstances, respectively. Speed was assessed by 30m speed test. Analysis of variance test and LSD post-hoc test was used.

Results: FG had significantly greater blood CRP (P<0/05) compared to other groups. However, differences between SG and TG were not significant. Muscle strength, and forearm and femur circumstances were greater in FG than other groups. Furthermore, this was greater in SG than TG. But chest circumstance was greater in FG and SG than TG only. There were no significant differences in speed between groups.

Conclusion: ASs consumption for muscle strength and volume improvement in bodybuilders is accompanied by higher level of CRP (as a cardiovascular risk factor).

Abstract
Background and Aim: Aging process is associated with increased free radicals and cellular damage. However, resistance training may cause balance of the oxidative and antioxidant system in the elderly. Therefore, the aim of this study was to investigate the effect of eight weeks of progressive resistance training (PRT) on malondialdehyde (MDA) concentration and superoxide dismutase (SOD) enzyme activity in inactive elderly women.
Materials and Methods: 26 inactive elderly women voluntarily participated in present study and divided into progressive resistance training (PRT; n=13) and control group (Con; n=13). The PRT performed resistance training for eight weeks (three sessions per week). Blood samples were collected before and after 8 week of progressive resistance training and analyzed for MDA concentration and SOD activities. 
Results: Results showed that after eight weeks of progressive resistance training, MDA concentration significantly decreased in the PRT compared to the control group (p=0.001). Also, SOD activity in the PRT was significantly increased compared to the control group (p=0.002).
Conclusion: The present study showed progressive resistance training cause reduction in malondialdehyde concentration and increase activity of superoxide dismutase that is an important factor in reducing aging process. Therefore, it seems that the regular resistance training causes to balance the oxidant system and reinforcement the antioxidant system in the body and can play a role in preventing serious damage that caused by oxidative stress, especially in aging.

Volume 15, Issue 1 (3-2021)
Abstract
Background and Aim: Excessive production of free radicals and the accumulation of oxidative damages play an important role in accelerating the aging process. However, one of the ways to fight against aging and related diseases is through physical activity. The aim of the present study was to investigate the effect of 12 weeks of resistance training on oxidative stress indicators (8-iso-prostaglandin-F2α: 8-iso PGF2α) and oxidative DNA damage (8-hydroxydeoxyguanosine: 8-OHdG) in elderly men.
Materials and Methods: In this quasi-experimental study, 30 elderly men were selected voluntarily and purposefully as a statistical sample and were randomly divided into experimental (n=15) and control (n=15) groups. Participants of the experimental group performed resistance exercises three sessions per week for 12 weeks. At the beginning and end of the study, serum levels of 8-iso PGF2α and 8-OHdG were measured by ELISA method. Correlated and independent t-tests were used to compare intragroup and intergroup means, respectively.
Results: Serum values of 8-iso PGF2α (P=0.007) and 8-OHdG (P=0.013) decreased significantly after 12 weeks of resistance training. Also, there was a significant difference between the experimental and control groups in serum values of 8-iso PGF2α (P=0.009) and 8-OHdG (P=0.02).
Conclusion: It seems that 12 weeks of resistance training reduces the values of oxidative stress (8-iso PGF2α) and oxidative DNA damage (8-OHdG) indicators in older men. Therefore, regular resistance training can play an important role in preventing injuries caused by oxidative stress, especially in old age.

The Effect of 8 Weeks Combined Training (Aerobic-Resistance) at Home with Quinoa Seed Supplementation on FBS, Appetite and Quality of Life in Women with Type 2 Diabetes
Nillofar Moradi, Mohammad Azizi, Elham Niromand, Worya Tahmasebi,
Volume 16, Issue 3 (8-2022)
Abstract
Background and Aim: Diabetes is a multifactorial disease characterized by chronic high blood sugar and insulin resistance. In general, the global increase in the incidence of type 2 diabetes is caused by poor nutrition and inactivity. Therefore, the aim of this study was to evaluate the effect of 8 weeks of combined exercise with quinoa supplementation on fasting blood sugar, appetite and quality of life in women with type 2 diabetes.
Materials and Methods: In this study, 36 women with type 2 diabetes were divided into 3 groups: exercise+supplement (n=12), supplement (n=12) and control (n=12). The exercise+supplement and supplement group consumed 25 grams of cooked quinoa seeds for 3 days a week. The exercise+supplement group also did combined exercise for 8 weeks, 3 times a week. Exercise was performed with an intensity of 10-12 pressure perception. The Persian version of the quality-of-life questionnaire was used to measure the quality-of-life index and the appetite questionnaire was used to assess appetite. Blood samples were taken 48 hours before and after the interventions, measurements and questionnaires were completed. One Way ANOVA, LSD post hoc and paired t were used at the significance level of P≤0.05.
Results: According to the results of 8 weeks of intervention in the exercise+supplement group (P=0.001)(2.59%) and the supplement group (P=0.04)(1.54%) compared to the control group (P=0.32)(1.54%) caused a significant reduction in Fasted blood sugar. There was also a significant decrease in appetite index in the exercise+supplement group (P<0.001)(54.20%) and the supplement group (P=0.001)(60.31%) as compared to the control group (P=0.11)(7.91%). Quality of life data also showed a significant increase in this index in the exercise+supplement group (P=0.008)(5.95%) and supplement group (P=0.002)(3.80%) as compared to the control group (P=0.10)(0.99%).
Conclusion: Eight weeks of combined exercise with consumption of quinoa seeds has a positive and improving effect on fasting blood sugar index, quality of life and appetite in patients with type 2 diabetes.

Volume 18, Issue 1 (3-2024)
Abstract
Background and Aim: Adipokines imbalance causes pathological effects on this system. Exercise interventions can play an important role in regulating the secretion of adipokines. This study aimed to investigate the effect of 12 weeks of resistance training on the serum level of apelin, vaspin, and blood pressure in elderly men with hypertension.
Materials and Methods: In this quasi-experimental study, 24 elderly men with high blood pressure were selected purposefully and based on the inclusion criteria and were randomly assigned to resistance training (N=12) and control (N=12) groups. The participants of the resistance training group performed resistance training for 12 weeks and three days a week. At the beginning and end of the study, blood samples were collected to measure the serum level of apelin and vaspin. Data analysis was performed using SPSS version 24 software with dependent and independent t-tests at a significant level of less than 0.05.
Results: After 12 weeks of resistance training, there was a significant decrease in the serum level of apelin (P=0.002), vaspin (P=0.01), systolic blood pressure (P<0.001), and diastolic blood pressure (P<0.001) as compared to the pre-test. In addition, a significant difference was observed between the two experimental and control groups in the serum level of apelin (p=0.001), vaspin (P=0.001), systolic blood pressure (P<0.001), and diastolic blood pressure (P<0.001).
Conclusion: It seems 12 weeks of resistance training can improve systolic and diastolic blood pressure and regulate the secretion of adipokines apelin and vaspin in elderly men with high blood pressure.
